Vulcan Materials Company Violates Terms of its Conditional Use Permit at
the Azusa Rock Quarry

Vulcan Materials Company's ability to mine at the Azusa Rock Quarry is
dependent upon their compliance with the conditional use permit. The conditional
use permit specifies which areas can be mined and how those areas are to be
reclaimed when mining operations are completed. Save Our Canyon has determined
that Vulcan Materials Company has violated the terms of their conditional use
permit by mining outside the specified boundaries. The map below shows the area
in which mining is permitted.

A satellite photo of the area shows how the landforms correspond to the
contour map:

A similar angle, seen from the ground shows that the corner outside the
boundary has already been mined:

A photo of the east side of the quarry from the west shows that Vulcan
has already mined the area outside of the current boundary. Coincidentally,
they have applied to extend the eastern boundary by another 250 feet to the
east.

Vulcan has continued to mine right up to the western border. The problem is
that the latest mining has been done at an slope of ~70°, although the
maximum slope allowed is 51°. At this point, it is not possible for
Vulcan to reclaim the latest mining without extending beyond the present CUP
boundary.
